THE DISTILLATION' ALCOHOLIC AND OTHER 1 The Schedule referred to in these Letters Patent and maln'ng part of the same To all whom it may concern:

Be it known th'at I, JAMES B.- MASON, of Chapel fiilhlin-thecounty of Orange and- State. of North Carolina, have invented a'n Improved Gold-cap Still; fox-the Distillation of Alchoholic andfOther Liquids,

and I' hereby declare the following tobe a full and exact description of the same,'reference' being had to part of this specification, in which- Figure l isafperspective view of myinvention.

The-still should possess a large heating surface, so

- a s to raise the liquid to the vapolizing' point in a short time and without having too great a temperature, atanyone point which would occasion the burning of the contents. a. i

This is often the case. with'the stills of the ordinary construction', when the'distillation is urged too much, and is' entirelyavoided by my invention by the'form of the body of the still, which is a low prism. with rectangular base and top, "and also by projecting within the body of the still-heating tubes,-

will take place injurious to the quality of the spirits produced, besides a loss in time and fuel.

This 'isaccomplished in "my invention by the manner of construoting and placing the cap,-which is so placedthatthe vapors enter: it almost assoon as formed, and are immediately condensed. i

y 4 For this purpose the cap is'kept cold by means of a cold-water vessel, and also by separating the cap from the body of the still bymeans of a non-conduct iugcompositiou which prevents the passage of heat from the,stil1 to the cap. p

. By this arrangementthe vapors are rapidly withdrawn when formed, and being at once condensed, all

pressure in the still is prevented. This in turn'hastens the evaporation, and, as a consequence, the yieldof distillate in a given time and for a given amount of fuel, is largely inereased' Tofenable othersto make and use my invention I will proceed to deseribeia i In the drawing-,9 H y is thebodyofthe sti1i,made in thezformshown in fig. 1.

The cap B, which may be single or duplicated any 'number'of times, as required, is divided by a'partition, b, so as to formv a cold-water vessel immedi ately over the still.

At the base of the cap is aciroular flange '0, highest where it joins the neck of the cap 0, so as to form main body or cap proper of the may be formed around the neck of the cap, or instead of these, any suitable device may be employed whereby a barrier "ofnon-conducting material may be interposed between the body of the still and the cap, the object being to ,keep the cap as cold as possible; Y

The top of the cap is kept fined with coldwater, which is constantly renewed.

the worm-tub or to some other vessel. The form of the still gives a large heating surface. v e y V This is further increased by the heaters H, which project from the fire space'into the body-of the still, as shown in figs. 2 and 3. a

These heaters are'placed directly under the caps. They are connected with each other by the pipes orflues h.

These heaters materially aid in produeingevapora- "tion, and being directly under the opening to the cap, prodiicethe vapor near the pointwhere it can be taken ed with the least delay. a
